NOTES:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ (MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD (MAX) = (TJ
(MAX)-TA)/θJA. Exceeding the maximum allowable power
dissipation produces an excessive die temperature, causing
the regulator to go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.

switching current spikes from inducing voltage noise in the part. The exposed
pad is also connected to VSS.
Over-voltage protection. Use a voltage divider to program the OVP threshold.
When the OVP voltage reaches the shutdown threshold of 1.2V, the switch
turns off and recovers when the OVP voltage decreases sufficiently. When the

OVP OVP voltage (with respect to VSS) is lower than 0.4V, and the FB voltage is
lower than 0.1V, the chip recognizes this as a short-circuit condition, and the
operating frequency folds back. Program the OVP voltage from 0.4V to 1.2V for
normal operation.
LED current feedback input. The MPQ2483A regulates the voltage across the
current-sensing resistor between FB and VSS. Connect the current-sensing
resistor from the bottom of the LED strings to VSS. FB is connected to the

0.6V turns the chip on. Both DC and PWM dimming are implemented on
EN/DIM. When the EN/DIM voltage (with respect to INGND) rises from 0.7V to

Open LED Protection
OPERATION
If the LED is open, there is no voltage on FB. The
The MPQ2483A is a current-mode regulator. The
error amplifier (EA) output voltage is proportional
to the peak inductor current.
duty cycle increases until OVP-VSS reaches the
shutdown threshold set by the external resistor
divider. The top switch turns off and remains off
until the voltage on OVP-VSS decreases
sufficiently.
At the beginning of a cycle, M1 is off. The EA
output voltage is higher than the current sense
amplifier output, and the current comparator’s
output is low. The rising edge of the 1.35MHz
CLK signal sets the RS flip-flop. Its output turns
M1 on and connects SW and the inductor to the
input supply.
Dimming Control
The MPQ2483A allows for both DC and PWM
dimming. When the voltage on EN is less than
0.6V, the chip turns off.
For analog dimming, the LED current changes
from 0% to 100% of the maximum LED current
when the voltage on EN is between 0.7V and
1.4V. If the voltage on EN is higher than 1.4V, a
maximum LED current is generated.
The increasing inductor current is sensed and
amplified by the current sense amplifier. Ramp
compensation is summed to the current sense
amplifier output and is compared to the error
amplifier output by the PWM comparator. When
the sum of the current sense amplifier output and
the slope compensation signal exceeds the EA
output voltage, the RS flip-flop is reset, and M1 is
turned off. The external Schottky rectifier diode
(D1) conducts the inductor current.
For PWM dimming, the VDIM-VINGND amplitude
must exceed 1.4V. The PWM frequency is
recommended to be in the range of 100Hz to
2kHz for optimal dimming linearity.
Output Short-Circuit Protection
If the sum of the current sense amplifier output
and the slope compensation signal does not
exceed the EA output for the entire cycle, then
the falling edge of the CLK resets the flip-flop.
The MPQ2483A has output short-circuit
protection. When the output is shorted to VSS,
the voltage on OVP (which detects the output
voltage) drops to under 0.4V. FB cannot sense
any voltage (<0.1V) since there is no current
running through the LED. In this condition, the
operating frequency is folded back to decrease
power consumption.
The output of the error amplifier integrates the
voltage difference between the feedback and the
0.198V reference. The polarity is a FB voltage
lower than 0.198V, which increases the EA
output voltage. Since the EA output voltage is
proportional to the peak inductor current, an
increase in its voltage also increases the current
delivered to the output.

Setting the Operating Frequency
Also note that the maximum recommended load
current is 2A if the duty cycle exceeds 35%.
The resistor on RSET is used to set the operating
frequency. A 1nF capacitor is recommended to
bypass RSET to GND.
Selecting the Input Capacitor
The input capacitor reduces the surge current
drawn from the input supply and the switching
noise from the device. The input capacitor
impedance at the switching frequency should be
less than the input source impedance to prevent
a high-frequency switching current from passing
through the input. Ceramic capacitors with X5R
or X7R dielectrics are recommended highly
because of their low ESR and small temperature
coefficients. For most applications, a 4.7µF
capacitor is sufficient.
The relationship between the operating
frequency and the RSET resistor is shown in the
curve in Figure 2. A 20kΩ to 200kΩ RSET
resistor is recommended to set the operating
frequency from around 1.35MHz to 250 kHz.
Leaving RSET open sets the operating frequency
to the default 1.35MHz.
Selecting the Output Capacitor
The output capacitor keeps the output voltage
ripple small and ensures a stable feedback loop.
The output capacitor impedance should be low at
the switching frequency. Ceramic capacitors with
X5R or X7R dielectrics are recommended for
their low ESR characteristics. For most
applications, a 2.2µF ceramic capacitor is
sufficient.

Selecting the Inductor
Selecting VSS-INGND Positive Spike-
Protection Circuit
A 1µH to 47µH inductor with a DC current rating
at least 25% higher than the maximum load
current is recommended for most applications.
For high efficiency, the inductor’s DC resistance
should be less than 200mꢀ. Refer to Table 1 on
page 13 for suggested surface mount inductors.
For most designs, calculate the required
inductance value with Equation (2):
In some applications, such as input power-on,
LED+ can short circuit from LED+ to VSS in both
buck boost and boost applications. When INGND
and VSS are not connected, there is a potential
risk that VSS-INGND can have a >0.3V positive
spike, which may cause false actions or damage.

PCB Layout Guidelines
To clamp the VSS-INGND positive spike, it is
recommended to add a 100ꢀ resistor from
INGND to input GND to clamp the current from
VSS to INGND. Add a low forward voltage
Schottky diode (e.g. B160) from VSS to INGND
to clamp the negative oscillation voltage (see
Figure 3). The voltage rating of the Schottky
diode should be higher than the OVP voltage set
by R3 and R4.
Efficient PCB layout is critical for stable
operation. For best results, follow the guidelines
below.
1. Place the high-current paths (VSS, VDD,
and SW) as close to the device as
possible with short, direct, and wide
traces.
For extremely high VSS-INGND spike conditions,
a bigger R2 and a higher current rating for D2 are
needed to clamp the current.
2. Place the input capacitor as close to VDD
and VSS as possible.
3. Place the external feedback resistors next
to FB.
INGND
VSS
4. Keep the switch node traces short and
away from the feedback network.

Figure 3: VSS-INGND Positive Spike-Protection
Circuit
Selecting the FB Positive Spike-Protection
Circuit
In applications where there is a possibility that FB
can have an abnormally high positive spike, such
as load transients from high to low, or LED+ short
circuit from LED+ to LED- in buck, boost, and
buck-boost applications, an abnormally high
positive spike on FB can create false actions or
damage.
To protect FB from positive spikes that are too
high, it is recommended to add a 10kꢀ resistor
between LED- and FB to clamp the current from
LED- to FB, and to add a <2V voltage range
Zener diode (e.g. BZT52C2V0) from FB to VSS
to clamp the voltage from FB to VSS (see Figure
4).
